They are recruiting subjects in the field rather than in the classroom, using field goods rather than induced valuations, and using field context rather than abstract terminology in instructions. We argue that there is something methodologically fundamental behind this trend. Field experiments differ from laboratory experiments in many ways. Although it is tempting to view field experiments as simply less controlled variants of laboratory experiments, we argue that to do so would be to seriously mischaracterize them. What passes for "control" in laboratory experiments might in fact be precisely the opposite if it is artificial to the subject or context of the task. We propose six factors that can be used to determine the field context of an experiment: the nature of the subject pool, the nature of the information that the subjects bring to the task, the nature of the commodity, the nature of the task or trading rules applied, the nature of the stakes, and the environment that subjects operate in. http://www.aeaweb.org/articles/article_detail.php?journal=JEL&volume=42&issue=4&article=1&issue_date=December 2004 10.1257/0022051043004577 American Economic Association Nashville, TN 0022-8282 Journal of Economic Literature http://www.aeaweb.org/journal.html 42 4 December 2004 http://www.aeaweb.org/articles/issue_detail.php?journal=JEL&volume=42&issue=4&issue_date=December 2004 Journal Article Job Information Networks, Neighborhood Effects, and Inequality Yannis M.Ioannides LindaDatcher Loury 1056 1093 This paper explores the theoretical and empirical literature to examine the use by different social groups of informal sources of information provided by friends, relatives, and acquaintances during job search and its consequences for the job market. It also addresses the role of network structure and size, the resource endowments of contacts, and nature of the links between contacts to explain differences in the effects of job information networks. In doing so, the paper also turns to the sociology literature on job information networks and provides an economic perspective on such sociological concepts as strong versus weak ties, inbreeding, distance from structural holes, etc. The paper distinguishes between models of exogenous job information networks, that is where individuals obtain job-related information through a given social structure, and endogenous job information networks, which are social networks that result from individuals' uncoordinated actions. The paper pays special attention to such issues as physical and social proximity and sharing of information and discusses them in the context of the recent social interactions and neighborhood effects literature. Finally, the paper outlines a model that integrates job information networks, where interactions occur in business cycle frequencies, with the dynamics of human capital formation, which include the joint effects of parental, community and neighborhood human capital, and are set in life cycle frequencies, for the purpose of organizing suggestions for future research and examining earned income inequality. http://www.aeaweb.org/articles/article_detail.php?journal=JEL&volume=42&issue=4&article=2&issue_date=December 2004 10.1257/0022051043004595 American Economic Association Nashville, TN 0022-8282 Journal of Economic Literature http://www.aeaweb.org/journal.html 42 4 December 2004 http://www.aeaweb.org/articles/issue_detail.php?journal=JEL&volume=42&issue=4&issue_date=December 2004 Journal Article Financial Crises: Review of Eichengreen and Tirole StanleyFischer 1094 1097 http://www.aeaweb.org/articles/article_detail.php?journal=JEL&volume=42&issue=4&article=3&issue_date=December 2004 10.1257/0022051043004612 American Economic Association Nashville, TN 0022-8282 Journal of Economic Literature http://www.aeaweb.org/journal.html 42 4 December 2004 http://www.aeaweb.org/articles/issue_detail.php?journal=JEL&volume=42&issue=4&issue_date=December 2004 Journal Article Review of The New Financial Order by Shiller Stephen A.Ross 1098 1101 http://www.aeaweb.org/articles/article_detail.php?journal=JEL&volume=42&issue=4&article=4&issue_date=December 2004 10.1257/0022051043004522 American Economic Association Nashville, TN 0022-8282 Journal of Economic Literature http://www.aeaweb.org/journal.html 42 4 December 2004 http://www.aeaweb.org/articles/issue_detail.php?journal=JEL&volume=42&issue=4&issue_date=December 2004 Journal Article The Unity of Auction Theory: Milgrom's Masterclass EricMaskin 1102 1115 http://www.aeaweb.org/articles/article_detail.php?journal=JEL&volume=42&issue=4&article=5&issue_date=December 2004 10.1257/0022051043004586 American Economic Association Nashville, TN 0022-8282 Journal of Economic Literature http://www.aeaweb.org/journal.html 42 4 December 2004 http://www.aeaweb.org/articles/issue_detail.php?journal=JEL&volume=42&issue=4&issue_date=December 2004 Journal Article Book Reviews 1116 1168 http://www.aeaweb.org/articles/article_detail.php?journal=JEL&volume=42&issue=4&article=6&issue_date=December 2004 10.1257/0022051043004568 American Economic Association Nashville, TN 0022-8282 Journal of Economic Literature http://www.aeaweb.org/journal.html 42 4 December 2004 http://www.aeaweb.org/articles/issue_detail.php?journal=JEL&volume=42&issue=4&issue_date=December 2004 Journal Article Annotated Listing of New Books 1169 1281 http://www.aeaweb.org/articles/article_detail.php?journal=JEL&volume=42&issue=4&article=7&issue_date=December 2004 10.1257/0022051043004531 American Economic Association Nashville, TN 0022-8282 Journal of Economic Literature http://www.aeaweb.org/journal.html 42 4 December 2004 http://www.aeaweb.org/articles/issue_detail.php?journal=JEL&volume=42&issue=4&issue_date=December 2004 Journal Article JEL Classification System 1282 1293 http://www.aeaweb.org/articles/article_detail.php?journal=JEL&volume=42&issue=4&article=8&issue_date=December 2004 10.1257/0022051043004559 American Economic Association Nashville, TN 0022-8282 Journal of Economic Literature http://www.aeaweb.org/journal.html 42 4 December 2004 http://www.aeaweb.org/articles/issue_detail.php?journal=JEL&volume=42&issue=4&issue_date=December 2004 Journal Article Doctoral Dissertations in Economics Ninety-Ninth Annual List 1294 1318 http://www.aeaweb.org/articles/article_detail.php?journal=JEL&volume=42&issue=4&article=9&issue_date=December 2004 10.1257/0022051043004603
